Are you looking to modify the PNG on the server
or the client within the browser ?
If you want to modify Server side then look at the GD library. Here
are two good links for that
www.libgd.org/Main_Page
- GD - Open Source library
www.codebeach.com/index.asp?tabID=2&categoryID=13&subcategoryID=4
- GD Tutorials
If you want to modify within the browser you might
consider use of an ActiveX component like our own
MetaDraw 3 OCX ( see www.Bennet-Tec.com) , or ImageMan ( from
DataTechniques www.Data-Tech.com ).
* MetaDraw will allow resizing, drawing / annotation, ..
by client side script or even ( if you allow ) by the
end-user with his mouse within the browser. * ImageMan
is great for things like Resizing, Rotation, Color depth
manipulation, Gamma correction, ...
